    I'm lucky to get an hour and 20 minutes these days. I understand batteries deteriorate over time, but for a year old battery to drop that much? The health of the battery is supposedly "good". Right now I'm on 40%, and I'm getting 40 minutes. That is with everything on idle.

    I've calibrated the battery a few times this month. I'm disappointed how quickly it has lost its charge - just back in the end of June it was retaining over 2 hours worth. Now it barley makes it over an hour.

    613 cycles is a lot in a year.

    I have 56 cycles on the MBP in my sig, which is 9 months old.

    I assume that is 613 'charged to discharged' cycles? I do use it on battery quite a lot (at University), but I didn't think it would be that much!

    Yep. I'm not sure what the exact rating of the batteries are in cycles, but you're close. Time for a new one. You can always keep the other for a spare to get you an extra bit of time.

    Is it possible having a battery with such a bad charge capacity would have an impact on performance/heat? It is a wild question to throw out there, but whenever I charge my MBP, the fans seem to come on full blast a lot of the time for no apparent reason.

    I'm really considering selling this and replacing it when the next gen MacBook Pro. How much would you reckon (if I replaced the battery) would it resell for? It still has an extra year's warranty with the retailer I bought it from.
